BRAKE ATTACHMENT FOR CARS.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed October 2, 1908. Serial No. 455,824.

To all whom it may concern.'

Be it known that I, GEORGE FnownN, a citizen of the United States,residing at Pleasant Unity, in the county of Westmoreland and State ofPennsylvania, have invented a new and useful Brake Attachment for Cars,of which the following is a speciiication.

The object of the invention is to provide a device which may be attachedto the ordinary construction of mine car and which will, when in place,provide against travel of the car down a grade up which it is beingdrawn, should the car coupling break or its members become separated,and will also provide against such movement of an entire train of minecars should the traction cable break or the cable clutch devices uponthe ear fail to properly grip the cable. Hcretofore, such devices havebeen usually applied at the middle of the rear end of a car but such anarrangement is unsatisfactory inasmuch as the drag bar, which usuallyforms an element of such a device, travels along the track substantiallymidway between the rails thereofl and not infrequently strikes the cableand the wheels over which the cable travels either knocking the cablefrom the wheels or injuring the wheels in some manner. l therefore haveas one object of my invention, the provision of a de ice of this typewhich may be applied to the end sill of an ordinary mine car at anypoint along the sill so that the drag bar will travel over the track waybetween one of the rails and the cable.

Other novel features of the invention will appear in the course of thespecific description which is to follow and in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a mine carshowing my invention applied thereto, the invention being shown in sideelevation and partly in section, and Fig. 2 is a top plan view of thedevice applied to the car sill.

In the drawings, the car is indicated in general by the referencecharacter A and one end sill of the car by the reference character B,this being the sill to which the device embodying my invention isapplied. One of the track rails is shown in Fig. 2 of the drawings andindicated at C, and the cable at D.

The device embodying my invention comprises a body member which isattachable to the sill of the car, and a drag bar which is pivoted tothe body member, and said body member is comprised of a pair of plates 5provided each with a forward extension 6 at the upper forward corner,and a similar extension 7 at the lower forward corner, the plates beingbolted together and held in spaced relation with respect one to the oth`r by spacing blocks of which there are two, one block, namely the upperone, indicated by the numeral S boing bolted between the upper extension6 of the said plates 5 and the lower block, indicated by the numeral t),being bolted between the corresponding extension 7 and the lower cornerof the plates. T he rear ends of these blocks 8 and 9 terminate directlyrearwardly of the forward edges of the plates at which edges theextensions 6 and 7 are formed, and the said. extension 6 and theextension 7 together' with the blocks 8 and 9 bolted therebetweenrespectively are arranged to receive between them the end sill B of thecar, the extension (l and block 8 lying above the said sill and theextension 7 and the respective block 9 exten/rling beneath the sill.

The forward edges of the plates 5, when the device is placed upon a carsill, rests directly against the rear face of the sill and the blocks 8and 9 extend forwardly beyond the plane of the forward face of the sill,the forward end of the block 8 being formed with an opening 10 and inits under side with a rccess 11 indicated with the opening, and thecorresponding' end of the block 9 being formed with keyhole slot 12. Alocking pin 13 is inserted vertically through the openings 10 and 12, itbeing provided at its upper end with a head 14 which rests against theupper face of the end of the block 8, said pin being provided adjacentits lower end with a laterally extending stud 15 adapted to pass throughthe narrow portion of the keyhole slot, and to lie beneath the block 9when the pin has been properly inserted. This pin 13 engages with theforward face of the end sill B of the car when the device is in placeupon the said sill and, as will be readily understood, preventsaccidental displacement of the device.

The rear portions of the upper edges of the plate 5 are preferablyinclined downwardly and confined between the plates at the said edgethereof is a block 16 the function of which will be presently morespecifically described. The drag bar of the device is indicated by thenumeral 17 and at its upper and forward end extends between the plates 5beneath the block 16 and is pivoted as at 18 for vertical swingingmovement, the lower end of the block being` provided with a notch 19resulting in spurs 2G which are designed to bite into the ties of thetraclr way should the car to which the device is applied startbaclrwardly down lthe incline. The device is braced against the rear oithe sill B by means of angle plates 2l which are carried one by each ofthe plates 5, one wing oi' each angle late resting directly against therear face oi the said sill.

From an inspection of the drawings, it will be seen that in applying thedevice to the car sill, the pin i3 is raised until its stud l5 seats inthe recess il in the underside of the upper one of the bloclrs, when thedevice may be applied te the sill and the pin dropped to the positionshown in Fig. l of the drawings, the stud extending below the lower oneof t re two bloci s,'=the stud serving to prevent accidentaldisengagement of the pin and also to prevent its complete withdrawalfrom the d vice.

As will be observed from the drawings, the bloclr 16 is held rigidlybetween the side plates of the body member oia the device by means ofbolts 22, which are passed therethrough. One oi these bolts 22 islocated adjacent the inner or forward end of the block i6, and byremoving all oi the other bolts 22, the block may be swung upon thisbolt as a pivot, so as to provide for greater latitude oi movement ofthe drag-bar 17. By so arranging this block "i6 that it may be swungvertically, the device is adapted for application to cars having theirend sills located but a short distance above the trackway.

Vilhat is claimed is l. The combination with a car sill, of a bloclrformed with portions to extend above and below the sill, a pin passedhrough the l said portions forwardly of the sill, and a drag bar pivotedto the block.

2. ln a device of the class described, the combination with a car sill,of a block provided with portions to extend one above the sill and theother below the sill, a pin passed through the said portions forwardlyof the sill, a drag bar pivoted to the block, and means for limiting theupward swinging movement or the said bar.

S. in a device of the class described, the combination with a car sill,oi a block provided with portions to extend above and below the sill, alocking means connected with said portions and extending forwardly ofthe sill, and a drag bar pivoted to the blocl.

d. ln a device of the class described, the combination with a car sill,oi' a block provided with portions to extend above and below the sill, apin passed through the said ortions a stud carried b the pin one of themembers being formed with an opening for the passage oi the said pin andstud, and the other member with a recess to receive the stud, and a dragbar pivoted to the block.

5. ln a device of the class described, the combination with a car, of ablock removably secured to the car, and a drag bar pivoted to the blockand having a forked lower end, the prongs of the forli being verticallyalined.

6. ln a device of the class described, the combination with a car, of ablocl; removably secured upon the car, the said block being formed witha recess having a top wall, and a drag bar pi'voted at its upper end inthe recess, and having its upward swinging move ment limited by the saidwall of the recess.

ln testimony that l claim the foregoing as my wn, l have hereto aiiixedmy signature in the presence of two witnesses.
